속성 값

The integer ID of the PipelineBuffer assigned to the IDTSOutput90 object.

주의

This run-time property is primarily used as a parameter for the FindColumnByLineageID method of the BufferManager property to locate a column in a PipelineBuffer.

예

The following code example locates the output columns in a buffer using FindColumnByLineageID. The indexes of the columns are stored in an internal member array so they can be accessed using either the PrimeOutput method or the ProcessInput method.

int []columnIndex;
public override void PreExecute()
{
    IDTSOutput90 output = ComponentMetaData.OutputCollection[0];

    columnIndex = new int[output.OutputColumnCollection.Count];

    for(int x=0; x< output.OutputColumnCollection.Count; x++)
    {
        IDTSOutputColumn90 col = output.OutputColumnCollection[x];
        columnIndex[x] = BufferManager.FindColumnByLineageID( output.Buffer,col.LineageID);
    }
}

Private columnIndex As Integer() 

Public  Overrides Sub PreExecute() 
 Dim output As IDTSOutput90 = ComponentMetaData.OutputCollection(0) 
 columnIndex = New Integer(output.OutputColumnCollection.Count - 1) {} 
 Dim x As Integer = 0 
 While x < output.OutputColumnCollection.Count 
   Dim col As IDTSOutputColumn90 = output.OutputColumnCollection(x) 
   columnIndex(x) = BufferManager.FindColumnByLineageID(output.Buffer, col.LineageID) 
   x -= 1 
 End While 
End Sub
